The JGS12864W2101-12864 dot matrix LCD screen, as a common display module, involves multiple aspects in its manufacturing process. Below are some common processes:

Liquid crystal material selection and coating:

The selection of liquid crystal material is crucial for the performance of the LCD screen. The appropriate type of liquid crystal, such as TN (twisted nematic), STN (super twisted nematic), or TFT (thin-film transistor), must be chosen based on application requirements.

The liquid crystal material requires precise coating processes to ensure uniform distribution and stable alignment of liquid crystal molecules on the screen.

Glass substrate preparation:

The glass substrate is the base material of the LCD screen and must undergo pre-treatment processes such as cleaning and coating to improve surface quality and adhesion.

Coating processes typically include the deposition of ITO (indium tin oxide) films to form conductive layers for driving and controlling liquid crystal molecules.

Electrode and circuit fabrication:

Electrodes and circuits, including row electrodes, column electrodes, and related drive and control circuits, are fabricated on the glass substrate.

Electrode fabrication usually involves photolithography and etching processes to ensure precise positioning and shape.

LCD cell assembly:

The glass substrate coated with liquid crystal material is aligned and bonded with another glass substrate (typically with a color filter) to form the LCD cell.

During assembly, uniform distribution of liquid crystal molecules and sealing must be ensured to prevent leakage.

Drive circuit and control system integration:

The drive circuit and control system are connected and integrated with the LCD cell to enable driving and control functions.

This typically involves processes such as chip soldering, circuit board layout, and wiring.

Testing and calibration:

The LCD screen is tested for parameters such as brightness, contrast, and response time to ensure performance meets design requirements.

Necessary calibration and adjustments are made based on test results to improve display quality and stability.

Encapsulation and protection:

The LCD screen is encapsulated to protect it from external environmental interference and damage.

Encapsulation materials typically feature good light transmittance, heat resistance, and corrosion resistance.

Additionally, the manufacturing process of the 12864 dot matrix LCD screen may involve other special processes, such as backlight module fabrication and touchscreen integration, depending on specific application needs and design requirements.

The manufacturing process of the JGS12864W2101-12864 dot matrix LCD screen is complex and precise, requiring comprehensive consideration of material selection, process steps, performance testing, and other aspects to ensure the quality and performance of the final product.
